Answer:

Conversion and substitution

Step-by-step explanation:

One way to find out if the expression is true, we can convert all the percentages into their decimal equivalence.

60% = 0.6

10% = 0.1

6% = 0.06

Now let's substitute the values.

0.06 = 0.6 x 0.1

0.06 = 0.06

Since 0.06 is equal 0.06, this then proves that it is true.

What’s the pattern of -1, -8, -27, and -64
AURORKA [14]

Hello from MrBillDoesMath!

Answer:

a(n) = (-n)^3  where n = 1,2,3,...


Discussion:

The pattern  1,8,27, 64... is immediately recognizable as the the cube of the positive integers. But this question has a minus sign appearing before  each entry, suggesting we try this:


 - 1  =  (-1)^3

 -8  = (-2)^3

-27  = (-3)^3

-64  = (-4)^3

That's what the problem statement asked for . The answer is equivalently

-1 * (n^3)


Thank you,

MrB

Answer:

Hello!

Question 1: <u>What is an earthquake?</u> Answer: An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

Question 2: <u>What are faults?</u> Answer: In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements.

Question 3: <u>Why are earthquakes more likely to occur near faults?</u> Answer: Notice that many plate boundaries do not coincide with coastlines. Earthquakes can also occur far from the edges of plates, along faults. Faults are caused by all that bumping and sliding the plates do. They are more common near the edges of the plates.

Question 4: <u>What happens when the plates grind against each other? </u><u>Answer: </u>An earthquake is caused by the movement of Earth's crustal plates grinding against one another.

Question 5: <u>Is it true that when vibrations reach earth surface as earthquakes occur? </u>Answer: Yes! It's true that it vibrates near the earth surface!

Hope I helped! Ask me anything if you have questions! Brainiest plz. Hope You make a 100%! Have a nice day! -Amelia♥

A set of X and Y scores has a regression equation with a slope of b = 4. If the mean for the X values is MX = 2 and the mean for
Rom4ik [11]

Answer:

-2

Step-by-step explanation:

In a linear regression model we have the equation Y = b_{1}X + b_{0} that relates X and Y, where b_{1} is the estimator of the slope and b_{0} is the estimator of the Y-intercept. The coefficients b_{1} and b_{0} can be estimated with the equations:

b_{1} = \frac{S_{xy}}{{S^{2}}_{x}}

b_{0} = MY-b_{1}MX. Thus,

b_{0} = 6 - (4)(2) = -2
